Durable High Performance

xWave co-planar WaveGuides provide the ultimate RF performance ideal for applications ideal for applications across the cmWave (3 GHz to 30 GHz) and mmWave (30 GHz to 100 GHz) bands.


Co-planar WaveGuide trace between the DUT interface and tester interface (co-axial or WaveGuide) bypasses the PCB. The minimized number of transitions provides the best possible signal fidelity.


RF performance that was once only possible in engineering labs is now available for production test floors. Hybrid contactor or probe head solution utilizes the co-planar WaveGuides in combination with standard pogo pins for the non-RF signals, powers, and grounds.


There are several benefits that include the best possible signal integrity up to 100 GHz, a highly integrated solution, and robustness for high volume production.
